The woman, who has since been named online as Chava, was reported by the MailOnline to be an Israeli national who is the daughter of Polish Holocaust survivors.

Willcox has since expressed his regret over the remarks, tweeting:

Really sorry for any offence caused by a poorly phrased question in a live interview in Paris yesterday - it was entirely unintentional

In a statement, a BBC spokesperson said: Tim Willcox has apologised for what he accepts was a poorly phrased question during an in-depth live interview with two friends, one Jewish and of Israeli birth, the other of Algerian Muslim heritage, where they discussed a wide range of issues affecting both the Muslim and Jewish communities in France.

He had no intention of causing offence.

Over 3.7million joined in the protest in defiance of the terrorists who killed 17 people in three days.

Leaders from countries across Europe linked arms as they led the marches in Paris. Standing side-by-side with French president Francios Hollande were David Cameron, Spanish prime minister Mariano Rajoy, Israeli prime minister Benjamin Netanyahu, Palestinian president Mahmoud Abbas and Queen Rania of Jordan, among others.
